When methyl 2-bromobenzoate was used, 2-aminobenzamide
was isolated in 80% yield, indicating that the ester moiety was not
compatible with these reaction conditions.
3. Conclusions
An economical and eco-friendly copper-catalyzed selective
hydroxylation and amination protocol was developed. A variety of
phenols and aryl amines were synthesized from the corresponding
aryl iodides and bromides in moderate to high yields. The process
employing L-Que, a by-product of the rubber industry, was
conducted in water under air and validated on the 100 g scale, thus
constituting a practical and eco-friendly protocol.
